I don't think I've ever installed a printer's app on my Mac. I have a reflex against it. The Mac has decent support for printers and scanners built-in, so did you need an App at all?
That's one thing that bugs me about hardware companies -- they all want you to install their app to monitor/configure/bedazzle their hardware. But really, it probably is just going to work anyway. And a printer or a mouse shouldn't need much.
At least on a Mac. On Windows, sometimes the vendor apps are helpful, but usually it's still not absolutely needed (except maybe for GPUs...)
I also despise these apps but wanted to see if it had the automatic feed feature. This printer it turns out can fax using the automatic feed but can't scan. Which is fine but they had the opportunity to upsell me on a new printer with that feature but instead failed miserably.
I second this...in my experience, just the WebUI the printer spins up, and maybe grabbing drivers from their site has always been enough. I'll do anything in my power to avoid that cursed HP app. Although I'm sure there is good money in increasing app downloads, so maybe things have changed, especially on the consumer-side of things
